0, a three-storey house requires a frontage 102a of the garage 102, so that the load-bearing walls 101 cannot be arranged between the columns 100a as between the columns 100b.
Since a load on the second and third floors is applied above the floor, a large structural member is used for the pillar 100a, or only the first floor has a steel frame structure or an RC structure.

In recent years, in the construction of these houses and the like, joints and joints using joints, metal fittings, box hardware, etc. have been used for the purpose of labor saving and rationalization at the time of construction or improvement of the strength of wooden buildings. Accordingly, a joining structure and a joining method of structural members for joining a beam and a girder, a column and a beam, a trunk difference and a through column, and the like have been developed. Also, every year, including the Great Hanshin Earthquake, wooden houses are often severely damaged by earthquakes and typhoons, etc.In the joint structure of each structural member of wooden buildings, including strengthening of joints such as joints etc. Various joining structures and joining methods of structural members aiming at improving the structural strength of the entire building have been developed.

However, the above-mentioned conventional joining structures and joining methods of joining tools and structural members have the following problems. When metal fittings and hardware are used for joining structural members of a wooden building, it is necessary to attach metal fittings and hardware to the structural members, and fix the structural members to each other via bolts and nuts. In addition to lack of workability, the work at the time of construction is complicated and lacks workability. In addition, due to expansion and contraction of the wood, the fixing force is reduced in several years, play is easily generated, and the reliability of the joint strength is lacking. Since the joints of the structural members require physical strength such as bending, tension, compression, and shearing, the fittings and hardware used to join the structural members become large,
Heavy and lacks transportability, especially when working at height. When structural members made of wood are fixed to each other with bolts and nuts, the tightening force is reduced in several years due to the expansion and contraction of the wood, and play is likely to occur. There is a problem that it deteriorates and lacks reliability and durability.

In the conventional joint structure, since the joints of the structural members are pin-joined, the strength of the wooden building is insufficient, requiring bracing, structural plywood, steel braces, and the like. At times, the brace breaks or comes off and may not fulfill its original role, and lacks reliability. In the case of Japanese-style houses or Sukiya-style houses with open layouts, bracing and load-bearing walls can be provided in open layouts such as large openings, wide rims, and continuations between Japanese rooms. The center of gravity of the building and the center of the bearing wall are separated from each other, and the building itself tends to shake greatly in the event of an earthquake or the like, and the building tends to collapse. There was a problem that lack of safety and security.

In a three-story house as shown in FIG. 10, a garage 102 is provided on the first floor, so that the pillar 100a
A bearing wall cannot be placed between the garage and the garage 1
A load on the second and third floors is applied above 02, and it is highly likely that the load will be destroyed from the pillar 100a of the garage 102 in the event of an earthquake, and lacks earthquake resistance and safety. Furthermore, since the bearing wall 101 cannot be formed at the frontage 102a of the garage 102, the
The whole house is likely to shake due to the vibration of the third floor to the third floor, and in this case, there is a possibility that the cloth of the wall of the third floor may be distorted or torn. Furthermore, when a large-sized structural member is used for the pillar 100a, or when only the first floor is made of a steel frame structure or an RC structure, there is a problem in that it takes time and effort to construct the building, lacks in building workability, and raises costs. .

Further, the publications A to C have the following problems. In each of the publications A to C, after connecting members (connected members) with bolts and nuts, the bolts are formed through holes or recesses into which the adhesive formed on the bolts is injected (distributed). Since the adhesive is filled between the outer peripheral surface and the bolt hole where the bolt is inserted and the members are joined,
Unless the bolt hole through which the bolt is inserted is penetrated between the members to be connected, the members cannot be connected (joined) to each other. Bolts and nuts cannot be used, and lack versatility and usability. In addition, when joining a beam and a column, as shown in Japanese Patent Application Publication No. C-3, after a common joint is inserted into a connected material and the connected material is abutted, the connected materials must be joined with bolts and nuts. In addition, "joint" members are required in addition to bolts and nuts, which increases the number of parts and lacks handling and joining workability.

The present invention solves the above-mentioned conventional problems, and provides a connector having a simple structure, excellent joining workability, significantly shortening the construction period, and having high structural strength.
In addition to being able to improve the structural strength of wooden buildings, it can also be added to buildings and seismic reinforcement of existing buildings, it is excellent in earthquake resistance and safety, and it is excellent in safety during construction work, and it is versatile and unskilled However, the joining structure of structural members that can easily and reliably join with excellent joining strength, and the workability of construction can be significantly improved, and the joining technology for structural members can be simplified, the number of work steps can be reduced, and the construction period can be significantly shortened It is an object of the present invention to provide a method for joining structural members that can be performed.

[0012]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, a connector according to the present invention, a joining structure of a structural member using the same, and a joining method of the structural member have the following arrangements. The connector according to claim 1 of the present invention,
a. A body having a tightening head at one end, a male screw formed at the other end of the body, and a hollow formed substantially in the longitudinal direction of the axis of the body; An adhesive injection port communicating with the hollow portion from the end surface of the body portion on the fastening head side, and a hole 1 communicating with the hollow portion from the outer peripheral surface of the body portion.
A plurality of adhesive outlets, and a connector body having:
b. A buried member having a female screw portion to which the male screw portion is screwed, and a fixing hole formed in the buried member substantially perpendicular to a longitudinal direction of the female screw portion. ing.

Accordingly, the following functions are provided. (1) When joining between members such as between wood or laminated wood, between wood and laminated wood, or between wood and stone or concrete, an insertion portion is formed to communicate with the member to be joined from the outer peripheral wall of the member. Inserting a buried member of the connector into the bottom side of the insertion portion, inserting the fixing member into the fixing hole of the buried member from the outer peripheral wall side of the member, and fixing the buried member in the insertion portion; By simply inserting the body part from the opening side of the insertion part and screwing the male screw part to the female screw part of the buried member, the members can be easily connected and joined by the joining tool. (2) Since a hollow portion is provided in the longitudinal direction of the body portion of the connector main body and an outlet for the adhesive is formed so as to communicate with the hollow portion, the adhesive is provided from the inlet to the hollow portion. The adhesive can be filled between the outer peripheral surface of the body portion of the joining tool and the peripheral wall of the insertion portion of the member into which the joining tool has been inserted by injecting the adhesive, and the members are securely fixed to each other with the adhesive. And can be rigidly joined. (3) Since the male screw portion of the connector body is screwed to the female screw portion of the embedded member fixed in the insertion portion, a space is provided between the peripheral wall of the insertion portion of the member and the outer peripheral surface of the body portion of the connector body. When the adhesive is injected from the injection port of the joint body, the adhesive can be substantially uniformly filled between the outer peripheral surface of the body portion and the peripheral wall of the insertion portion of the member, and the joining can be performed. The bonding effect between the tool and the member can be improved, and the members can be securely bonded to each other. (4) Since the embedding member has the female screw portion to which the male screw portion of the joint body is screwed, the outer diameter of the embedding member is larger than the body portion of the joint body. The diameter of the fixing hole formed and the fixing member inserted into the fixing hole can be increased, and the strength of the fixing member and the fixing force of the embedded member when the embedded member is fixed in the insertion portion can be improved. And the joining strength between the members can be improved. (5) When joining members using a plurality of joining tools,
It is possible to reduce the outer diameter of the body portion and the buried member of the joining tool main body, thereby reducing cross-sectional defects of the member and preventing a reduction in the strength of the member. (6) Since the connector made of a metal or other high-strength member is buried and fixed with an adhesive in the insertion portion for inserting the connector formed on the member, it is possible to maintain a high-shear, high-tension rigid joint. Also, since the embedded member of the connector is fixed in the insertion portion by the fixing member inserted into the fixing hole, the embedded member can be firmly fixed in the insertion portion by the shearing force and toughness of the fixing member, and the member The toughness of the joint between them can be improved. (7) The embedded member is inserted into the insertion portion formed in the member, and the fixing member is inserted into the fixing hole of the embedded member from the outer peripheral wall side of the member to fix the embedded member in the insertion portion. By inserting the connector body from the opening side of the connector and screwing it to the female thread of the embedded member, the members can be pulled together and the contact surfaces of the members can be brought into close contact, and the adhesive can be injected from the injection port In this case, it is possible to prevent the adhesive from leaking from the abutting surfaces of the members, and the members can be securely adhered to each other and joined. (8) In particular, when joining the pillar and the lintel, a buried member is inserted and fixed to the lintel side of the insertion part formed in communication with the lintel from the outer peripheral wall of the pillar, and After inserting the connector body from the opening of the insertion part and screwing the male screw part of the body part into the female screw part of the buried member, just inject the adhesive from the injection port into the hollow part, the pillar and the lintel Can be joined firmly,
The strength of the opening between the columns can be improved,
Deformation of the frame due to horizontal force can be prevented.

Here, the material of the joining tool is not only iron products such as stainless steel, chromium, steel and carbon steel, and metals such as aluminum alloys, but also organic materials such as carbon fiber, boron fiber, glass fiber and metal fiber. Or what is processed with inorganic fiber and synthetic resin is used. The body of the connector body has a circular cross section, a substantially elliptical shape,
It may be formed in an arbitrary shape such as a substantially polygonal shape such as a triangle, a quadrangle, and a hexagon. As the fastening head of the joint body, a member having a shape capable of engaging a tool or the like with the fastening head and screwing the joint body to the embedded member, such as a nut-shaped fastening head, is used. In addition, the fastening head is detachably attached to one end of the body, such as a male screw formed on one end of the body and a fastening head made of a nut or the like screwed to one end of the body. The attached one may be used. The male screw portion may be formed by a predetermined length from the other end of the body portion, or may be formed over the entire length of the body portion.

The discharge port and the injection port of the adhesive communicating with the hollow portion of the joint body and the hollow portion are about 1/20 to 16/20 times, preferably about 1/2 times the outer diameter of the body of the joint body. 1 /
The cross section is formed in a substantially circular shape having a diameter of 10 to 5/10 times. In addition, depending on the viscosity of the adhesive and the material of the joining tool, as the diameter becomes smaller than 1/10 times the outer diameter of the body portion, the fluidity of the adhesive in the hollow portion is reduced, and the time for injecting the adhesive is reduced. There is a tendency that the mechanical strength of the body of the connector body is impaired as the ratio becomes larger than 5/10 times.

The discharge port is formed in the diametrical direction of the body of the connector body so as to communicate with the hollow portion. Also, the discharge port is 2
When formed as described above, it may be formed so as to communicate with the hollow portion and penetrate in the diametrical direction of the body portion, or may be formed substantially radially around the hollow portion. When two or more discharge ports are formed, the adhesive injected into the hollow portion is discharged from the plurality of discharge ports, so that the time for injecting the adhesive can be reduced. Further, when the discharge port is formed at a symmetrical position from the hollow portion, the adhesive injected into the hollow portion can be discharged almost uniformly to the outer peripheral surface of the joining tool, and uneven filling of the adhesive can be prevented. When the joining body is inclined downward from the upper surface of the member, the ejection port is formed on the male screw side of the body, and the joining body is inclined upward from the lower surface of the member. When inserting the discharge port, it is preferable to form the discharge port on the side of the body where the head is fastened. Thereby, the adhesive can be evenly filled between the outer peripheral surface of the joint body and the peripheral wall of the insertion portion of the member into which the joint is inserted.

The buried member depends on the material and the like of the buried member.
m, preferably 4 mm to 12 mm. As the difference between the outer diameter of the buried member and the outer diameter of the torso of the joint body becomes smaller than 4 mm, it depends on the material of the member, the type of adhesive, the construction time (summer and winter), etc. When the bonding agent is inserted into the insertion portion and the adhesive is injected, the adhesive discharged from the discharge port is filled with the adhesive between the outer peripheral surface of the body portion of the bonding device main body and the insertion portion. There is a tendency that it is difficult to flow between the peripheral walls, and as the difference from the outer diameter of the body of the joint body becomes larger than 12 mm, there is a tendency that more adhesive is required than necessary, and the outer diameter of the buried member and These tendencies become stronger when the difference from the outer diameter of the body of the connector body is smaller than 3 mm or larger than 15 mm. Furthermore, the buried member is formed in any cross-sectional shape such as a circle, an ellipse, a polygon such as a square or a hexagon. Note that a long nut may be used as the buried member. Thereby, the workability of forming the embedded member can be remarkably improved, and the cost of the connector can be reduced.

The fixing hole of the embedded member is preferably formed to have a size of 0.3 to 0.8 times the outer diameter of the embedded member. In addition, as the fixing hole becomes smaller than 0.3 times the outer diameter of the embedded member, the outer diameter of the fixing member inserted into the fixing hole also becomes smaller, and the shearing force of the fixing member decreases and the embedded member is inserted. There is a tendency that the fixing force of the embedded member when it is fixed in the part and the rigidity when the members are joined with the joining tool are reduced, and as the fixing hole becomes larger than 0.8 times the outer diameter of the embedded member, Since the fixing hole formed in the embedded member becomes large, the strength of the embedded member tends to decrease. The female screw portion of the embedded member may be formed over the entire length of the embedded member, or may be formed between one end of the embedded member and the fixing hole. As the fixing member, a rod-shaped pin, a nail, a screw such as a lag screw, a coach screw or the like, which is formed in a size that can be inserted into the fixing hole according to the fixing hole, is used. When a commercially available nail, screw, or the like is used, the cost of the connector can be reduced.

After the members are joined to each other with a conventional joining metal fitting such as a U-shaped box metal fitting or a hook-shaped metal fitting, an insertion portion is formed in each member to insert a buried member of the joint fitting. The fixing member is inserted into the fixing hole of the embedded member from the outer peripheral wall side of the member to fix the embedded member in the insertion portion, and the connector body is inserted from the opening side of the insertion portion to embed the male screw portion. The members may be screwed into female threads of the members, and an adhesive may be injected into the hollow portion of the connector body to solidify the members. In this case, after the members are temporarily fixed with the joining bracket, the members can be joined with the joining tool, and the joining workability of the members can be improved, the joining accuracy can be improved, and the contact surfaces of the members are brought into close contact with each other. It is possible to reliably prevent the leakage of the adhesive, to maintain the joining strength such as shearing and tension of the members with the joint in addition to the joint, and to use the joint with the joint. The joint can be reduced in size, and furthermore, even if one of the joint and the joint is damaged by an earthquake or the like, it is possible to prevent the building from being completely destroyed.

Here, the adhesive outflow preventing portion is formed of a collar formed on the end surface of the tightening head on the side of the torso larger than the outer diameter of the insertion portion. Such as a washer disposed between the part and the member, the opening diameter of the insertion part is formed larger than the outer diameter of the opening of the insertion part. A shape that can be closed is used. When the fastening head is formed of a nut having an outer diameter larger than the outer diameter of the insertion portion, the fastening head may be used as an adhesive outflow preventing portion.

According to a third aspect of the present invention, there is provided the connector according to the first or second aspect, wherein the connector main body comprises:
A head member having the fastening head at one end and having a joint at the other end, one or more trunk members having a body joint at both ends, and a other end having a joint at one end And a tip member having the male screw portion.

(10) By joining the head member, the trunk member, and the tip member in this order at each joint, the joint body can be easily formed, and the joint body can be easily formed according to the number of body members to be joined. Can be arbitrarily changed in length. (11) Particularly, when the discharge port is formed on the male screw portion side of the joint body, a hollow portion is formed in each of the head member, the body member, and the distal end member, and the discharge port communicates with the hollow portion of the distal end member. By forming a hollow portion and a discharge port in the tip member, the hollow portion of the connector body can be formed by dividing each member, so that the forming distance of each hollow portion can be shortened. In addition, even when the discharge port is formed on the male screw portion side of the joint body, the hollow portion and the discharge port can be easily formed.

Here, the joining portion and the body joining portion are formed in such a manner that each member can be detachably joined, such as those having a female screw or a male screw, those having a fitting concave portion or a fitting convex portion. Is used. Alternatively, only the head member and the tip member may be joined at each joint to form a joint body. Also,
The hollow portion is formed up to the discharge port so as to be substantially straight in the longitudinal direction of the connector body when the respective members are connected. In addition, when the discharge port formed in the body portion of the joint body is formed on the male screw portion side, the distance of the hollow portion formed in the body portion becomes longer,
Further, if the formation distance of the hollow portion is too long, the formation of the hollow portion becomes impossible. Therefore, when the discharge port is formed on the male screw portion side, it is divided into a head member, a body member, and a tip member. The connector body is preferably used.

According to a fourth aspect of the present invention, there is provided the connector according to any one of the first to third aspects, wherein the outer peripheral surface of the body is formed into a thread-shaped or irregularly shaped rebar-shaped uneven surface.

Thus, in addition to the functions of the first to fourth aspects, the following functions are provided. (13) When an adhesive is injected into the hollow portion of the joint body,
The adhesive discharged from the discharge port of the joint body can be substantially uniformly filled along the spiral member between the outer peripheral surface of the joint and the peripheral wall of the insertion portion of the member into which the joint is inserted, and Can be prevented, and uneven filling of the adhesive can be prevented. Thus, the members can be firmly consolidated, and an adhesive having a high viscosity can be easily filled without unevenness. (14) Since the spiral member is externally fitted to the body of the joint body, the spiral member can be embedded and fixed together with the joint in the insertion portion of the member with the adhesive. The joint can be used as a reinforcing material, and the shearing and tensile stress at the joint between the members can be improved.

According to a sixth aspect of the present invention, there is provided the connector according to any one of the first to fifth aspects, wherein the sealing body having a projection fitted into the inlet is provided. It has a configuration provided.

Thus, in addition to the functions of the first to fifth aspects, the following functions are provided.

Even when the adhesive which takes a long time is injected into the hollow portion, it is possible to prevent the adhesive from leaking from the injection port before the adhesive is cured, and to securely solidify the members. (16) Since the injection port can be sealed with the sealing body, the fastening head can be covered with the sealing body, and the appearance of the insertion portion of the member can be improved.

Here, the sealing body only needs to have a projection that can be fitted into the injection port, and may have a shape that can cover the tightening head of the connector body, or the projection may be provided with the injection port. For example, a connector that is formed so as to be flush with the surface of the member into which the connector body is inserted when fitted into the connector.

(B) By injecting the adhesive into the hollow portion from the inlet of the joint body, the adhesive is discharged from the outlet of the joint body, and is bonded between the outer peripheral surface of the joint and the peripheral wall of the joint insertion portion. Agent can be filled, and the structural members can be consolidated. (C) Only by forming the connector insertion portion and the fixing member insertion portion in the structural member, the structural members can be firmly joined to each other by the connector and the adhesive, and the joining structure of the structural members can be simplified. (D) Since a connector having extremely high mechanical strength is embedded in each structural member and the structural members are securely connected to each other and joined, the resistance of the structural members to bending, tension, compression, shearing, etc., is reduced. Can be improved. (E) Since the embedded member of the connector is fixed in the connector insertion portion by the fixing member, the embedded member can be firmly fixed by the shearing force of the fixing member, and the joining strength of the structural member can be improved. Due to the toughness of the structural member, the toughness of the joint between the structural members can be improved. (F) When the connector body is inserted at a predetermined inclination angle with respect to the contact surface of the structural member, it can withstand deformation due to a vertical load, and the rigidity of the structural members can be improved. (G) When the connector insertion portion is formed in a cross shape between the structural members, the structural members can be connected and held only by inserting the connector main body into the connector insertion portion, and the structural members can be connected to each other. The joining operation can be easily performed, and the joining body is screwed to the embedded member fixed in the joining portion with the fixing member, and an adhesive is injected into the joining body to fix the structural members together. The loads from the upper, lower, left and right sides of the member can be canceled out by the couple of the respective joining tools, and joining with extremely excellent mechanical strength can be achieved. (H) Since the joint is embedded in the structural member and the outer peripheral surface of the joint is covered with the adhesive, it is possible to prevent the joint from being oxidized and the like, and to improve the durability of the joint. . (I) The joining tool is inserted into the joining section of the structural member to join the structural members to each other, and further, an adhesive is filled between the outer peripheral surface of the joining section and the peripheral wall of the joining section to join the structural members. Structural members can be rigidly joined to each other, improving the joint strength.Also, they are solidified with an adhesive, which can absorb the expansion and contraction of structural members such as wood and reduce backlash. Can be prevented. (J) Since the joints between the structural members have a rigid frame structure that is firmly joined with a joint and an adhesive, the frontage (span) of the building can be significantly widened without using load-bearing walls or braces. A space without pillars can be obtained.

The connector insertion portion is formed inside the outer peripheral wall surface of the structural member at a position 1.1 to 6 times the outer diameter of the embedded member, depending on the size of the structural member. The connector insertion portion is arranged such that the outer diameter of the embedded member is 1.1 mm from the outer peripheral wall surface of the structural member.
As the position becomes smaller, the end and the surface of the structural member are likely to be damaged when a large external force is applied to the structural member. And it tends to be difficult to improve the joining force between the structural members. Also, the size of the connector insertion portion is 3 mm to 15 m from the outer diameter of the body of the connector main body.
m, preferably 4 mm to 12 mm, and a size that allows the embedded member to be inserted and fixed. Depending on the material of the structural member and the type of adhesive, etc., as the difference between the outer diameter of the connector insertion portion and the outer diameter of the body of the connector body becomes smaller than 4 mm, the type of adhesive and the construction time (summer, Although it depends on the winter season, the adhesive discharged from the discharge port tends to be less likely to flow between the outer peripheral surface of the body portion of the joint body and the peripheral wall of the joint insertion portion, and the outside of the body portion of the joint body is As the difference from the diameter becomes larger than 12 mm, there is a tendency to require more adhesive than necessary,
Further, when the difference from the outer diameter of the body portion of the joint body is smaller than 3 mm or larger than 15 mm, these tendencies become even stronger. When the spiral member is externally fitted to the body of the connector body and the connector body and the spiral member are simultaneously inserted into the connector insertion portion, it depends on the outer diameter of the spiral member, the spiral interval, and the like. A size that allows the spiral member to be inserted into the connector insertion portion and allows the adhesive to flow between the body of the connector body and the peripheral wall of the connector insertion portion (for example, 0 mm or more from the outer diameter of the spiral member). The connector insertion portion is formed with a diameter of 15 mm larger). Further, when the joint insertion portion is formed to be larger than the outer diameter of the embedded member, the adhesive can be filled also between the outer peripheral surface of the embedded member and the peripheral wall of the joint insertion portion, and the embedded member is inserted into the joint insertion portion. It can be fixed with an adhesive, and the fixing force of the embedded member can be improved. Further, the connector insertion portion is formed in an arbitrary cross-sectional shape such as a polygonal shape such as a circle, an ellipse, a square and a hexagon.

When the structural member is subjected to a particularly large external force at its tip, such as a horizontal cantilever, or when joining a climbing beam, etc., the connector insertion portion is formed to have an inclination angle α. Is preferred. The inclination angle α is set to 20 ° ≦ α <90 °, preferably 20 ° ≦ α ≦ 70 °, more preferably 30 ° ≦ α ≦ 60 ° with respect to the contact surface. Although it depends on the material of the structural member and the size of the connector, the inclination angle is 3
As the angle becomes smaller than 0 °, the position of the connector insertion portion approaches the end (contact surface side) of the structural member, and the structural member tends to be easily damaged by a large external force, and the inclination angle is 60 °.
As the size becomes larger, the length of the connector tends to be too long and the workability tends to be reduced, and the inclination angle is 20 °.
The smaller the value, the stronger these tendencies become.

In particular, when the connector insertion portion is formed from the upper outer peripheral wall side of the structural member, the connector main body of the connector can be easily inserted into the connector insertion portion from above the structural member, and the work can be performed. In addition to improving the performance, the fastening head of the joint body can be prevented from being exposed to the lower outer peripheral wall of the structural member, and the appearance can be improved, and between the outer peripheral surface of the joint and the peripheral wall of the joint insertion portion. The adhesive can be reliably filled. In addition, another connector insertion portion is perforated so as to be cross-shaped with the connector insertion portion at a predetermined interval on the contact surface of the structural member to be joined, and the connector is inserted into each connector insertion portion. When the members are joined, loads from the top, bottom, left, and right, such as tension, bending, and shearing, of the joined structural members can be canceled out by couples of the joining members, and the joining force between the structural members can be improved. Furthermore, by forming the connector insertion portion with an inclination angle α or forming a cross shape, the connector can be used even in the case of a two-way rigid frame structure or when there are structural members in three or four directions. Structural members can be joined together.

The fixing member insertion portion is substantially the same size as the fixing hole of the embedded member, and is formed at a position where the fixing member can be inserted into the fixing hole of the embedded member inserted into the connector insertion portion. Further, the fixing member insertion portion may be formed so as to penetrate through the structural member, or may be formed to have a predetermined depth in communication with the connector insertion portion. One end side of the fixing member insertion portion may be formed to have a large diameter so that the portions can be fitted. Further, after the fixing member is inserted into the fixing member insertion portion, a plug such as a wooden plug may be driven into the opening of the fixing member insertion portion so as to be flush with the outer peripheral wall surface of the structural member. Thereby, the appearance of the structural member can be improved. As the adhesive, an epoxy resin adhesive, a polyurethane adhesive, a vinyl acetate resin adhesive, or the like is used.

Thereby, it is possible to prevent the adhesive from overflowing from the air vent portion before the adhesive is filled between the outer peripheral surface of the joint and the peripheral wall of the joint insertion portion, and it is possible to reliably prevent the outer peripheral surface of the joint and the joint insertion portion from being filled. The adhesive can be filled between the peripheral walls. The air vent portion has an arbitrary shape such as a substantially circular shape, a substantially elliptical shape, and a polygonal shape such as a quadrangle, and is pierced in such a size that the adhesive can be smoothly injected. Further, after the adhesive overflows from the air vent portion, if the diameter of the air vent portion is large, a plug such as a wooden plug may be driven in to make the flush with the outer peripheral wall surface of the structural member. Thereby, the appearance of the structural member can be improved.

It has one or more seat portions, and has a configuration in which an opening side of the seat portion is embedded and an embedding material whose surface is substantially flush with an outer peripheral wall surface of the structural member is provided.

Thus, the following operation is obtained in addition to the operation of the seventh or eighth aspect. (M) Since the fastening head of the connector body can be brought into contact with the seat, the fastening head can be prevented from protruding significantly from the surface of the structural member, and the appearance of the structural member can be improved. It is possible to prevent the adhesive from leaking from the contact surface between the fastening head and the seat. (N) By embedding an embedding material on the opening side of the seat portion, it is possible to prevent the tightening head of the connector main body from being exposed on the surface of the structural member, and in particular, by using a carbonized film of the structural member in a fire or the like. The joint can be protected from the high temperature of a fire and safety can be improved. (O) Since the embedding material is substantially flush with the outer peripheral wall surface of the structural member, the appearance of the structural member can be improved. (P) Since the fastening head of the joint body is embedded in the structural member with the embedding material, external heat can be prevented from being transmitted to the joint, and the external heat is transmitted to the structural member through the joint. Transmission to the inside can be prevented.

Here, as the embedding material, a material having a projection which can be inserted into the injection port of the connector body is used. The projection is inserted into the injection port to seal the injection port and to open the seat. The side may be buried.

Excellent bonding workability. (9) By loosely screwing the male screw portion of the connector main body to the female screw portion of the embedded member and leaving looseness between the structural members to be joined, the workability of assembling other structural members can be improved. (10) Since the horizontal structural member and the structural member have an air vent portion communicating with the connector insertion portion, when the adhesive is injected into the hollow portion of the connector, the air inside the hollow portion or the connector insertion portion is used. Is discharged from the air vent and the adhesive can be filled smoothly, and by confirming that the adhesive overflows from the air vent when the adhesive is injected, the adhesive is bonded between the outer peripheral surface of the joint and the peripheral wall of the joint insertion part. It can be confirmed that the agent has been filled. (11) Inserting the connector into the connector insertion portion formed on each structural member to join the respective structural members, and filling an adhesive between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion. Since the structural members are consolidated, the structural members can be rigidly joined, and the resistance of the structural members to bending, tension, compression, shearing, and the like can be improved. (12) Since the joint is embedded in each structural member and the outer peripheral surface of the joint is covered with an adhesive, it is possible to prevent the joint from being oxidized and the like, and to improve the durability of the joint. In addition, expansion and contraction of the structural members can be absorbed, and rattling between the structural members can be prevented.

(2) Since the joining body is divided into a head member, a body member, and a tip member, a joining unit is formed by forming a unit hollow portion having a short length for each member when forming a hollow portion. The hollow portion of the main body can be formed, and particularly when the discharge port is formed on the tip end side, the hollow portion can be easily formed. (3) Since a spiral member such as a spring is externally fitted to the body portion of the joint body, and the joint body and the spiral strip member are inserted into the joint insertion portion, the adhesive is applied to the hollow portion of the joint body. When injected, the adhesive can be almost uniformly filled along the spiral member between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion from the outlet of the connector main body, and uneven filling of the adhesive can be achieved.
